Thanks for your input @jodar75.in advance hun! You're awesome for doing this.
TBH I'm not an avid DiY'er dear..
My starting shade was like a Jay Z / Kerry Washington shade. It took me a year to come up 5 shades, of course I hit bumps along the journey.
My favorite products that I use faithfully are Niacinamide (B3) USP powder. I must have it and I add 2 ounces to my Aveeno lotion
with the stir rod and use it quickly before it oxidizes, it still lightened my body even when it turned a little brown.
Lactic Acid 90% the 40 ounce bottle. and I use that every week or bi weekly with distilled water. I attempted to make a lotion, but it didn't work out to well. I'm not that good at DIYing. I order this products from Lotioncrafters
By the way I mix the all ready made lotions and oils like g&g etc , I didn't mean I make my serums, I use perfecting brightener serum for my face.
I'm afraid to make KJ serum,but look to try it when I have some time.
